Nelson Piquet's departure from the formula one team Renault is to be announced officially on Monday, according to the Brazilian newspaper O Estado de S.Paolo.
His replacement will be the similarly aged 23-year-old Romain Grosjean, who is Renault's 2009 reserve and a current GP2 driver.
The Sao Paulo newspaper said Piquet and his famous father-manager and namesake will also make a press statement on Monday.
Depending on the outcome of the Renault suspension appeal on August 17, the Swiss-French Grosjean will make his F1 debut alongside Fernando Alonso at either Valencia or the subsequent Belgian grand prix at Spa.
